A-110-4 – Blue

A-110-4 is a so-called Thru Zero Quadrature VCO. The term “quadrature” means in this connection that the oscillator outputs sine and cosine waveforms simultaneously. The term “Thru-Zero” means that even “negative” frequencies are generated. But this a bit a misleading term as negative frequencies do not really exist. “Negative” means in this connection simply that the sine/cosine waves will stop when the linear control voltage reaches 0V and continue with the opposite direction as the linear control voltage becomes negative and vice versa.

Important note: The owner manual advise you to remove the jumper “JP3” inside the module if you don’t expect to use the CV/Gate. In this case, with the keeped jumper, the module could be send noise interferences.
